You are running 2, 4 cell 5300 packs in paralell?? for 10,600 Arent two of them a little heavy?? around 1400 grams? Must abe able to run for a very long time. I thought the pursuit only needed one 4-cell around 4500 - 5000???

Running in Salt water

There's a little more maintinance when running in salt water. You've got to clear the cooling system with fresh water and then some WD40. Also the salt will take the shine off your hardware quickly.
I took my R30 to Maine with me and had a blast in the ocean except when I picked up seaweed. This happened several times and the steering goes away completely so, you may have to go get the boat.

Grim 45 X 68 lifter

The conditions from last weekend to this past weekend couldn't have been more different. Last weekend I clocked my Revolt at 42.6mph with an Octura X642 and the boat was hard to keep on the water due to the windy conditions.
This weekend I had both the X642 & the 45 X 68 lifter. I ran both, no wind, the X642 ran 42.6mph and the 45X68 ran 42.9. The lifter seemed noticably faster until I looked at the gps. The lack of any ripples on the water really seems to slow things down. Both props are ballanced & sharpened.
Both runs are with a Hyperion 4S 4200mah battery (new) and a Velocity RC GPS. The only adjustments I've made are to raise the strut until it was at "0" checked with a straight edge. I have also replaced the Collet & Flex shaft with OSE parts.

I've been flying helis for a couple years now but on occasion run my aquacraft Rio EP.
The Rio is brushed and not real fast so I would like to get a more upgraded faster brushless boat. With all the reviews I've read I've pretty much narrowed it down to the Revolt 30 or the new Impulse 31 V2 from Pro Boat.

The Impulse is a bit more money, but the ESC can handle 6s as long as you prop down. For my money, I would get the Revolt. I've heard they're easier to get handling nicely and are a bit faster out of the box.
